Figure 1. High density array of BiFeO3 nano-islands.

Figure 1

(a) The fabrication procedure of BFO nano-islands array illustrated by a SEM image of AAO and AFM topography image of BFO nano-islands. (b) High-resolution XRD patterns. (c) TEM cross-section image of BFO nano-islands on Nb:STO (100) substrate. The average diameter of the dome-shaped nano-islands is almost identical to the pore size of the AAO template.
